2.2.2.2. Cooked rice noodle sample
The 5 cm length noodle strips of each dried rice noodle sample were boiled in distilled water at 100 °C for 2, 4, 6 10 and 12 min. After boiling, the rice noodles were immediately cooled in water at room temperature for 1 min to stop further cooking. Excessive water on the surface of noodles was softly wiped off with a paper towel. The cooked rice noodles were cut into 10 mm × 5 mm pieces and were wrapped with LLD-PE film to prevent moisture loss and placed into a glass bin. The T2 values of water in the cooked noodle samples were measured using MRI with the same parameters that were used in the measurement of the known water content standard samples. Water distribution inside the cooked rice noodles at each cooking time was measured in triplicate and three noodle strands were measured for each replicate. After T2 measurement, the water contents of noodle samples were measured by oven drying at 100 °C for 24 h.
